Direct Energy Production From Hydrogen Sulfide in Black Sea Water - Electrochemical Study

A sulfide driven fuel cell is proposed to clean the Black Sea with the simultaneous A sulfide driven fuel cell is proposed to clean the Black Sea with the simultaneous production of energy. The process is hopeful even at low sulfide concentrations, i.e.10 to 25 mg/l being close to the ones in the Black Sea water. The main problem for the practical application of this type of fuel cell are the low current and power densities. The measurement of the generated electric current compared to the sulfide depletion show that the most probable anode reaction is oxidation of sulfide to sulfate. It is evident that parasite competitive reactions oxidation of sulfide occurs in the anode compartment of the fuel cell. The pH measurements shows that the transfer of hydroxylic anions from the cathodic compartment to the anodic one across the separating membrane is not fast enough to compensate its drop in the anode compartment

Identification and Molecular Characterization of a New Ovarian Cancer Susceptibility Locus at 17q21.31

Epithelial ovarian cancer (EOC) has a heritable component that remains to be fully characterized. Most identified common susceptibility variants lie in non-protein-coding sequences. We hypothesized that variants in the 3 ′ untranslated region at putative microRNA (miRNA) binding sites represent functional targets that influence EOC susceptibility. Here, we evaluate the association between 767 miRNA binding site single nucleotide polymorphisms (miRSNPs) and EOC risk in 18,174 EOC cases and 26,134 controls from 43 studies genotyped through the Collaborative Oncological Gene-environment Study. We identify several miRSNPs associated with invasive serous EOC risk (OR=1.12, P =10−8 ) mapping to an inversion polymorphism at 17q21.31. Additional genotyping of non-miRSNPs at 17q21.31 reveals stronger signals outside the inversion ( P =10−10 ). Variation at 17q21.31 associates with neurological diseases, and our collaboration is the first to report an association with EOC susceptibility. An integrated molecular analysis in this region provides evidence for ARHGAP27 and PLEKHM1 as candidate EOC susceptibility genes

Сhild-parent relationship as a predictor of youth’s financial activity

Introduction. The study of financial behaviour and human activity in relation to the management of material resources seems relevant both from the point of view of identifying potential risks of deviant behaviour patterns in this area, and identifying training opportunities for effective management of their own financial resources. The studies of financial behaviour of young people in conjunction with parent-child relationships are poorly presented in modern science and are conducted mainly abroad. Due to the lack of data, the value of the Russian research is great due to the high demand for scientific ideas about such relationship.The aim of the present research is to identify the interdependence between child-parent relationships and the financial activity of young people through the correlation of their models of financial behaviour, as well as the search for determinants of the activity of boys and girls in the system of parenting.Methodology and research methods. An empirical study was conducted on two related samples – youth representatives (young teenagers aged from 14 to 16 years old) and their parents. The total number of study participants was 144 people, of which 87 parents (57 women and 30 men) and 57 youth representatives (29 girls and 28 boys). For data collection, the authors compiled a questionnaire. This questionnaire contains two blocks: an assessment of the financial activity of the family and an assessment of the financial activity of youth. Also, the authors employed the methodology “Family Relationship Analysis” (by E. G Eidemiller, V. V. Yustitskis) and the questionnaire “Parent Behaviour and the Attitude of Children toward It” (by E. Schafer). Processing of the obtained data was carried out in the statistical package IBM SPSS Statistic 19.0. For mathematical and statistical analysis, the methods of descriptive statistics, cluster analysis, correlation analysis and regression analysis were used.Results and scientific novelty. As a result of an empirical study, two statistically significant regression models were constructed. According to the obtained models, some features of parent-child relationships really stimulate the financial activity and independence of youth. The groups of financially active and passive boys and girls are identified. It is established that these groups differ only in relation to their own assessments of parental impact by the mother.Practical significance of the work lies in the possibility of using the obtained data to form a scientific understanding of the genesis and mechanisms of formation of a person’s financial activity, as well as in identifying target groups and developing effective methods for teaching financial literacy of the population

FIB sputtering optimization using Ion Reverse Software

This paper experimentally demonstrates that a quantitative description of focused ion beam (FIB) milling (at least for several 3D profiles with inclination not higher than 45°) can be done by means of an isotropic local etching model. Specific characteristic of this model is that it does not account for re-deposition. The paper also presents IonRevSim – Software developed specifically for data preparation and prediction of the shape of the FIB machined structures. Those functions and their operating modes are discussed here in detail and FIB experimental results are provided to verify the algorithms embedded in the software

Fabrication and validation of fused silica NIL templates incorporating different length scale features

A cost effective methodology for pattering of Nano Imprint Lithography (NIL) templates incorporating different length scale features is proposed. The approach relies on selecting the optimum processing window of different technologies for cost effective micro- and nano-patterning. Very promising results were obtained when first fused silica templates were structured by F2 laser ablation at 157 nm. It was demonstrated that nano-scale features and complex 3D micro-scale features could be machined with a Focused Ion Beam (FIB) over the existing topography produced by laser ablation. Thus, a large area (up to several square centimeters) of the NIL templates is easily patterned with micro- and even meso-scale features by laser ablation while nano- and micro-scale features could be introduced locally by FIB machining. Through S-FIL process such templates were validated and the nano- and micro-structures were accurately replicated in one imprinting step

Length scale integration: Implementation of a new process chain for producing replication masters with micro and nano scale features

Emerging micro-engineered products tend to integrate a multitude of functionalities into single enclosures/packages. This trend for “function integration” has to be underpinned by manufacturing capabilities for “length-scale integration” at component and product levels, i.e. the ability to manufacture parts incorporating features from a few hundreds of micrometres to sub-100 nm. In order to design novel process chains that enable such function and length scale integration into miniaturised devices, it is required to utilise materials that are compatible with the various component manufacturing processes in such chains. At the same time, these materials should be able to satisfy the functional requirements of the produced devices. One family of materials, which can fulfil these criteria, is bulk metallic glasses. In particular, the absence of grain boundaries in bulk metallic glasses makes them mechanically and chemically homogeneous for processing at all length scales down to a few nanometres. A number of recent studies have shown that pico-second laser ablation and focused ion beam milling are promising technologies for structuring this type of amorphous alloys at the micro and sub-micro scales respectively without introducing any changes in their non-crystalline structure. In this context, this research presents an experimental investigation to establish the validity of the process pair “pico-second laser” and “focused ion beam” when it is considered for structuring a particular type of bulk metallic glasses to produce replication masters incorporating micro and nano scale structures
